We first spotted beta Pic d in new images from the Very Large Telescope (VLT), before then finding it in archival JWST + VLT data dating back as far as 2014 using new analysis techniques. It was hiding all along! This allowed us to observe its orbital motion. 📹 ESO/B. Sutlieff, M. Bonse et al. 🔭

Ten years of hide-and-seek! 🫣 Astronomers used our VLT to find a new #exoplanet orbiting the famous star Beta Pictoris — hiding in archival ESO observations spanning over a decade! And it's shyer than any exoplanet we've imaged before. 🔭 🧪 1/3 📷 ESO/B. Sutlieff, M. Bonse et al.

finding a black hole in a globular cluster is challenging, the dynamics are messy as all fuckity boo (to use the technical scientific terminology)

I really miss the Cassini mission.

Hi. We're in the Age of Diarrhea. I'm a global health expert on helping children survive diarrhea. Here's what to do if you might have picked up cyclospora. 🧵 1. Call your primary care if possible. 2. Take oral rehydration therapy, which isn't just drinking fluids. 1/

really think that if democrats hold any chamber of congress next year that a condition of passing a budget is the removal of russ vought, who has a genuinely tyrannical vision of presidential power and is a focal point of the lawlessness of the trump administration

"NSF employees are now concerned that the $1 billion of withheld funds will not be released. If they are not, the combination of withheld funds and clawbacks would result in funding cuts of more than 30% for most directorates compared with their planned spending for 2025"

#StarCity really ramped up in the second half of the season, delivering some of the best Cold War drama I've ever seen. Give it a watch, if you haven't already.

Kid vs. Squid was my first middle-grade novel. It's about a kid on summer vacation who makes friends with a survivor from Atlantis. They fight monsters. You probably haven't read it. But you could! Kobo: www.kobo.com/us/en/search... Amazon: www.amazon.com/Kid-vs-Squid...

Five facts that you should know about the current Cyclospora outbreak.

Baby stars growing up! 🌟 👶 Webb has turned its gaze to the star system FS Tau. Here, baby stars, 1 to 3 million years old, are forming from dense pockets of gas and dust. But one day, these babies will become fully-fledged stars 👉 esawebb.org/images/FS-Tau/ 🔭

lots of new people on my feed because of yesterday's jeremiad... and i feel some duty to give a little bit of a pep talk, because, yeah, i get it, that shit's kinda dire, so buckle up, here's the part where i tell you why it's worth it to deal with all the slings and arrows...

i believe that the the entire "binge watch" model of releasing television series is based on a faulty premise, and that faulty premise has significantly devaluated television as an art form. stick with me on this one...

No need to pixel stretch Hubble's images. The universe is creating its own kind of stretch—as seen in the Veil Nebula, the remnant of a star roughly 20 times as massive as the Sun that exploded about 10,000 years ago. Credit: ESA/Hubble & NASA, R. Sankrit.

A cosmic construction project 🏗️ Webb has observed a galaxy cluster in the making. Two sub-clusters, roughly equal in mass, are actively merging in this messy view. Several details come to light when looking closer 👉 esawebb.org/images/potm2... 🔭 🧪

Remember: The real freeloaders in this country are the rich — not the poor or immigrants or any other group of people vilified as scapegoats. The richest 1% evade over $160 billion in taxes every year. The United States literally has yacht and private jet tax deductions. Hello?

That’s one big chandelier… The @NASAHubble team captured this sparkling photo of the Chandelier Cluster, a globular star cluster within our Milky Way galaxy. A globular cluster is a dense collection of thousands to millions of stars bound by gravity. Original post

I'm currently working on map(s) of Titan. Part of this project is new basemap of Titan combining radar and infrared data. I still have a lot of work to do but the radar part is almost done.

TESS has identified its first planet through gravitational microlensing rather than transit: a super-Jupiter orbiting far from its star. More such planets may be hidden in nearly eight years of archived data. doi.org/hb892k

Wait, do people not understand this!! This shit means EVERYBODY.

NEWS: How did exoplanet WD 1856 b, which orbits less than 2 million miles from a white dwarf, survive the death of its star? New research using #NASAWebb holds clues, and may have implications for the future of our solar system: https://news.stsci.edu/3QfXJEg 🔭

🚨 Beyond the limit 🚨  New ESO study finds that current proposals to launch 1.7+ million satellites into orbit would have devastating consequences for astronomy. The most extreme proposals come from SpaceX & Reflect Orbital  🔭 🧪 ☄️ #DarkSkies #SatelliteConstellations 1/4

Is there an updated Habitable Worlds Catalog or something similar? I'm searching for the current number of how many we have found. #exoplanets 🔭

This dude is a crank who only succeeds at getting publicity, so basically this makes complete sense as part of the con job this administration continues to work against the US.
